This Ph.D. is currently a Tenured Full Professor at a major University.  His research focuses on the design, representation, simplification, compression, analysis and visualization of highly complex 3D shapes, structures, and animations.  His technical expertise and research interests span the modeling of 3D shapes and animations; 3D compression and progressive transmission of 3D shapes and animations; realtime direct-manipulation techniques for human-shape interaction and view control; and finally 3D graphics acceleration techniques including 3D model simplification, visibility culling, image-based rendering, and graphic hardware operations.  His contribution to 3D Graphics Acceleration includes the use of graphics hardware for rendering and inspecting CSG models and complex 3D assemblies and the Vertex Clustering 3D simplification approach, which has been incorporated into several products by IBM, SGI, and other companies to accelerate the rendering of complex 3D models. 

He has authored 21 patents (most on graphic acceleration and compression) and over 120 peer-reviewed technical articles for which he received 23 awards.  This Expert is an elected Fellow of the Eurographics Association.
